OIL-STOVE BURNER.

To all whom it may] concern.

Be it known that I, MAURICE C. Snnmon, acitizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Oil-Stove Burner, of which the following is a specification.

My invention relates to an improvement in oil burners for stoves and heating units, whereby the combustion of the fuel vapor results in a perfect blue-flame throughout the predetermined range of a varying fuel supply. The primary objects of my invention are, to provide a burner construction such that the heat of combustion will not cause the walls, particularly the inner ones, to buckle or warp; to provide means for firmly securing the component parts in proper relation, one to the other, and of securing the burner to its stove framework; to provide an arrangement of parts such tosecure an inflow of air, so directed as to obtain the maximum heat from a minimum quantity of fuel; to provide a construction insuring the rapid initial vaporization of the fuel such that no burning wick, starting wick, or asbestosrings or kindlers of any kind are required for the production of a blue flame, at once, following the lighting of the vapor, and a further object is to eliminate at all times the detrimental efiects of carbonization of the burner parts.

I accomplish the above and such other objects as may become apparent from the following descriptiomby the means shown in the accompanying drawing, in which- Fig. 1 is a side elevation of the burner. with fragments of the walls removed to show the inner construction. Fig. 2, is a top plan view, and Fig. 3, is a vertical section taken on the line 33 of Fig.

Like characters of reference indicate like parts throughout the. several views of the drawing.

The base 5, of the burner consists preferably of a casting having an annular channel 6 within for the purpose of receiving and holding the liquid fuel supplied to the burner through the supply pipe 7. An annular shoulder 8 is provided near the top of the outer side of the inner wall of the base 5 to form a seat for the inner cylinder 9, which fits snugly against the inner wall of the base 5.

Th y inder 9 ha top .0 as an int gr l part of its side wall. The side wall contains a series of perforations 11, but'thc top 10'is imperforate, with the exception of a single ring of holes 12, near the outer edge. A bolt 13, passes through the top 10. and has screw-threaded engagement in the member 141-, which member is a part of a stove frame, not shown, and upon which member 14: the base 5 rests. I

By turning the bolt 13, downwardly until its head contacts the top of the cylinder 9, the cylinder is pressed against the base in such manner that the two parts are rigidly held together and the base 5 is held firmly in contact with the frame member 14L.

An outer cylinder 15, pierced by a regular series of perforations, but having no top nor base, contacts the inner side of the outer wall of the base 5, and is supported on the annular shoulder 16. The base 5 is provided with a number of arms 17, radially projecting from the top edge of the outer wall of the base 5. To prevent displacement of the outer cylinder 15, and to maintain it firmly upon its shoulder 16, I provide fasteners 18, to hook over the edge ofthe cyl inder 15, and engage under each of the four arms 17. The fastener 18, with its upper hooks 23, is substantially in the form of a narrow U-shaped member of spring-wire, expanding somewhat above its middle portion into a'wider U and forming the corresponding angles 19, 20, 21 and 22, to provide elastic means of vertical extension of the fastener to enable it to exert a compressive downward pull on the cylinder 15, when it is hooked over the top and engaged under the arm 17.

The arms 17 are recessed on the top outer ends to provide seats to support and shoulders 2 1 to space an outer imperforate cylindrical shell 25 of a diameter greater than that of the cylinder 15 such that an annular opening 26 between the lower end of the shell 25 and the base 5 is effected. The upper end of the shell 25 is formed with a lip 27 inwardly projecting to form a cover or top to enclose the annular space between the shel and the cylinder 15. This lip 27 is provided with a single annular row of holes 28, just outside of the cylinder 15.

The holes 28 in the shell 25 and the holes 12 are important features of my invention contributing toward the perfect combustion of the fuel vapor regardless of the amount lUE of fuel supplied the burner in the annular channel 6 within predetermined limits. It is also to be noted that I employ cylindrical members and not conical members, such that all air spaces formed between the various walls are uniform in cross section from bottom to top. The amount of furl supplied the burner through the pipe 7 is regulated by a valve not shown such that the heat developed by the burner is regulated by operation of the valve.

What I claim as new and desired to secure by Letters Patent is:

1. In a burner employing hydrocarbon fuels in stoves and heating units, a supporting frame member; a burner base having an annular channel; a fuel supply pipe entering the channel; an inner cylinder open at the base, resting on said base, said cylinder having a plurality of perforations in its side wall and having a closed top with a single annular row of holes near its outer edge; means for securing said. base to said frame member extending through said in nor cylinder; an outer cylinder resting on said base without said annular channel, said outer cylinder being open at the top and having a plurality of perforation in its wall; elastic means of securing said outer cylinder to said base; an outer cylindrical shell forming an annular air space about said outer cylinder, said shell being supported by said base; and an inwardly projecting lip from the top of said shell to enclose at the top said annular air space, said lip having a plurality of holes through it.

:2; In a burner for oil stoves and heating units employing hydrocarbon fuels and having a fuel supply that may be varied, a supporting frame member; a burner base having an annular channel adapted to. receive and hold liquid fuel; a fuel supplypipe secured to said base; an inner cylinder open at its bottom and resting on said base, said cylinder having a plurality of perforations in its wall and having an integral top with a single annular row of holes near its outer edge; a bolt passing through the top of said inner cylinder and through said frame member; an outer cylinder being open at both ends and resting on said base around the outer edge of the channel in said base and having a plurality of perforations in its wall; a plurality of radially projecting arms from said base; an out-er cylindrical shell of a diameter greater than that-of said outer cylinder, said shell having its lower open end resting on recessed portions of said arms; an inwardly projecting lip to contact said outer cylinder top edge, said lip having a single row of holes near the line of contact of the lip with the said outer cylinder; and elastic means of securing said outer cylinder to said base.

3. In a burner for stoves and heating units employing liquid hydrocarbon fuels, a supporting frame member; a burner base having an annular channel adapted to receive and hold liquid fuel; a fuel supply pipe secured to said base an inner cylinder open at its bottom and resting on 'a shoulder formed in said base, said cylinder having a plurality of perforations in its wall and having a top secured to it, said top having a single. annular row of holes near its outer edge; a bolt passing through the top of said inner cylinder and through said frame member; an outer cylinder being-open at both ends and resting on a shoulder in said base such that the channel of said base is be tween said inner cylinder and said outer cylinder. said outer cylinder having a plurality of perforations through its wall; a plurality of arms projecting from said base; an outer cylindrical shell of a' diameter greater than that of said outer cylinder, said outer shell having itsllower end resting on said arms; an inwardly projecting lip to contact said outer cylinder top edge, said lip having asinglerow of holes near the line of contact of said lip with the said outer cylinder; and a plurality of fasteners hooking under said arms and over the top edge of said outer cylinder, said fasteners being substantially narrow'U shaped, eX- panding above their middle portion into a wider U shape to give a form whereby the fasteners may be vertically elastic to a limited degree.
